Xe graphics driver uses different graphics sysfs knobs including /sys/class/drm/card0/device/tile0/gt0/gtidle/idle_residency_ms /sys/class/drm/card0/device/tile0/gt0/freq0/cur_freq /sys/class/drm/card0/device/tile0/gt0/freq0/act_freq /sys/class/drm/card0/device/tile0/gt1/gtidle/idle_residency_ms /sys/class/drm/card0/device/tile0/gt1/freq0/cur_freq /sys/class/drm/card0/device/tile0/gt1/freq0/act_freq Plus that, /sys/class/drm/card0/device/tile0/gt<n>/gtidle/name returns either gt<n>-rc or gt<n>-mc. rc is for GFX and mc is SA Media. Enhance turbostat to prefer the Xe sysfs knobs when they are available. Export gt<n>-rc via BIC_GFX_rc6/BIC_GFXMHz/BIC_GFXACTMHz. Export gt<n>-mc via BIC_SMA_mc6/BIC_SMAMHz/BIC_SMAACTMHz.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
